By direct esterification of methylphenylcarbinol with propionic acid, using azeotropic conditions (Arctander, 1969)Общее описание
Styralyl Propionate is used widely in perfume compositions as a modifier for or a companion to - the Acetate. It may appear more versatile in that it is not restricted to Gardenia and is different from the almost vulgar effect derived from the Acetate ever since that material was first used in a successful perfume. Much of the effect of these two esters depends upon the skill and delicate hand used in a composition, the experience in determining just how much can be used to achieve a desirable and attractive effect after proper ageing of the fragrance composition. This ester works well with Dimethylbenzyl carbinyl acetate and related materials with Oakmoss, Clary Sage, Bergamot, Lina- 100I, Lavender, Jasmin, Galbanum, etc. It is also frequently used in flavor compositions, e.g., in the difficult Gooseberry and other berry imitations, fruit complexes, etc. The concentration used is normally about 5 to 15 ppm in the finished product.
